The world is in a state of relative peace and prosperity. A scholar stumbles on an old prophesy regarding a child who can see himself as he really is without becoming insane, and thus pass through the Wall of Glass separating the Eternal Vale from the Lands of Daranor. An apparition of Tivu the Cloudwalker signifies that the age has now come to pass, and the child now walks among men. The prophesy dictates that with the opening of the gateway, the lost Power of Air will return to the world. Tarthur sees this as a chance to rescue Yan and sets off in search of the child. But, unbeknownst to him, another mysterious creature is also hot on the trail. He is relentlessly pursuing the Power of Air for his own ends, and soon Tarthur begins not only to fear for his own life, but for that of his young son, who seems to be inexplicably caught up in the prophecy every step of the way.
